Fine - but the cameras rarely get a picture of the driver, and you get a ticket and fine assessed, plus a notation on your record without a trial.
I could put fake tags with your number on a car that looks like yours, run every monitored red light in the city, and you'd get a bunch of tickets that you'd have to pay - for offenses you didn't commit. Or you piss off your spouse when you're going through a divorce, and she runs all the lights in town in 'your' car. This has actually been done in at least two cases I can think of. You think that might be a problem? Something about "so much for the right of trial by jury"?
If I understand correctly, all the owner of the car has to do is reveal who was behind the wheel if it wasn't the owner of the car. The driver of the car at the time of the infraction then gets the ticket. If I'm wrong, please correct me.
Here in California, they won't even bother mailing the ticket if they can't ID the driver in the pic.
